JOSEPH L. MARQUIS, OF BUFFALO, NEW YORK.

BLUE-PRINT MACHINE.

Specification of Letters Patent.

Patented Nov. 20, 1917.

Application filed December 24;, 1913. Serial No. 808,618.

To all whom it may concern:

Be it known that I, JOSEPH L. MAR UIS,

a citizen of Switzerland, residing at Buffalo,

county of Erie, State of New York, have invented certain new and useful Improvements in Blue-Print Machines, ofwhich the following is a specification.

This invention relates to blue chines. v

One object resides in the provision of a fixed curved contact member with which cooperates a moving contact member and between which contact members the meeting faces of the work are maintained in close contact to insure a perfect print.

Another object resides in the provision of a peculiarly formed or constructed fixed contact surface embodying such characteristics as will obviate some of the disadvantages experienced in the use of glass and other contact surfaces.

With the above and other objects in View,

print mathe present invention consists in the combination and arrangement of'parts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes may be made in the form, proportion, size and minor details without departing from the spirit or sacrificing any of the advantages of the in- Y vention.

In the drawings Figure 1 is a perspective view of the invention with parts broken away.

Fi .2 is a fragmentary transverse sectiona view.

Referrin now more particularly to the accompanying drawing, the reference character A indicates a frame of any suitable form and material and preferably including two tables 1 and 15.

At the .forward end of the framework of the machine are brackets a upon which the aforesaid table 1 is preferably mounted and adjacent the inner ends of which brackets are preferably arranged frame rings 6 and which are arranged preferably between the tables 1 and 15.

Disposed between the tables 1 and 15 and preferably in horizontal alinement with the aforesaid rin wire mesh through which the printing light isadapted to penetrate. This fixed contact surface is secured to rings 8 which are prefis a fixed curved contact, 'surface'6 which may be composed of fine erably of a size substantially the same as the aforesaidframe rings 6. The rings 8 are preferably connected in spaced relation by three rods 10, lland 12, upon which said fine wire screen or other mesh material 6 is secured in any suitable manner. surface 6 is preferably stretched tightly over 'the end rings 8 and clamped thereon by means of straps 9 and said rings may be supported between the rings 1) in any suitable manner. The fine screen or other mesh material 6 may be stiffened and supported by the diamond shaped metal frame work 7 which may be clamped on the surface 6 by the straps 9 or in any other suitable manner. The fine wires of the-screen or mesh material are preferably not parallel to the direction of movement of the material through the machine but they are preferably disposed at an angle and in such a way that the part of the drawing covered by a wire becomes uncovered the next instant and so does not show on the resulting print. The printing light is preferably of the electric arc variety and may be suspended from the hooks d on the beam D supported by the uprights E- The lights are preferably let down. into the fixed contact surface through the open upper side thereof.

Ooeperating with the fixed contact sur-- face thus formed is a feeding belt or moving contact surface 4 which is arranged to travel in close contact with said fixed contact surface 6. This moving contact surface is pref- The I erably in the form of an endless belt which.

works over four rollers 19, 20, 21 and 22 and it may be driven in any suitable manner. The rollers 19, 20, 21, and 22 are preferably mounted in suitable brackets 30' secured in any suitable manner. to the framework A of the machine. Secured in eye-bolts 51 preferably directl over the roller 19 is a rod 50. On this rod 50 I mount a guide 5 which is preferably composed of a thin sheet of brass, one end of which is fastened around the rod 50 with its other end let in loosely between the'movas f them on to the exposed or fixed contact surthe rod 55, facilitating the discharge of the drawing and sensitized paper on to the table 15. i i The fixed contact surface having its body formed of fine screenor mesh material has properties and advantages over glass. It

' fixed member may be made more trans arent than lass. It will not crack or brea because of cat. One of the most important features of this particular character of contact surface is that tracings will not slip as they frequently do on glass surfaces. This slippmg iscaused apparently by the electrification of the glass.

What is claimed is 1. A blue fixed member composed of fine wire mesh and affording a curved contact surface and amoving member having a contact surface for carrying the work through the machine in engagement withthe fixed curved contact surface, the wires of the meshf bein inclined to the direction of the movement 0 the material through the machine.

2. A blue print machine comprising a fixed member composed of fine wire mesh and affording a curved contact surface and a moving member having a contact surface for carrying the work' through'the machine in engagement with the fixed contact surface and 1n a direction substantially." at right angles to the longitudinal axis of the fixed contact surface, the fine wires of the wire mesh being inclined to the direction of movement of the material through the machine.

'3. -A blue print machine comprising a composed of fine wire; mesh and afiordin moving mem er havin' a contact surface for carrying the work t rough the machine I 1n engagement with the fixed contact surface and 1n a direction substantially at right print machine comprising a a work throu a curved contact surface, a

angles to the longitudinal axis of the fixed contact surface, the fine wires of the wire mesh being inclined to the direction of movement of the material through the machine, and a metal frame work composed of wire mesh stretched tightly over the aforesaid wire mesh and whose wires are inclined angles to the longitudinal axis of the fixed contact surface, the fine wires of the wire mesh being inclined to the direction of movement of the material through the machine, a

lamp support, and a lamp suspended from' I said support to throw rays of light into said fixed member through said opening in the top thereof; a

5. A blueprint machine comprising a fixed member composed of fine wire mesh affording a contact surface, a moving memberhavmg a contact surface to carry the gh the machine in en agement with the fixed contact surface, the of the fixed member being inclined to the direction of movement of the material through the machine, and a strengthening member for said fine wire wires of the mesh being inclined to the direction of the movement of the material through the machine.

In testimony whereof I ,aflix my signature in presence of two 'witn.
